Potential Conferences
You can look for disciplinary conferences or divisions of your disciplinary conferences. For instance, Communication has panels for Instructional Development Division and a Scholarship of Teaching and Learning papers for our National Communication Association annual conference. We also have interest groups such as Communication Education for Central States Communication Association and Instructional Communication for Eastern States Communication Association.
Likewise, Psychology has the Society for the Teaching of Pscyhology at Midwestern Psychological Association Conference.
So, certainly consider your "normal" disciplinary venues.
There are also conferences devoted just to teaching or SoTL work such as:
The annual FACET Retreat, held in May each year, is an IU system wide combination of "retreat" (inspiritational, self-discovery, fun) types of events with interactive workshops and presentations of research related to teaching
Midwest Scholarship of Teaching and Learning Conference at IU South Bend
International Society for the Scholarship of Teaching and Learning Conference (ISSOTL)
Illinois State's list of SoTL related conferences including their own
Lilly Conferences on College and University Teaching are held annually in Oxford, OH; Travis City, MI; Bethesda, MD; Newport Beach, CA; and Austin, TX: these conferences welcome a variety of submissions from posters and presentations of research to interactive workshops and roundtable discussions.
